Darius the 1st and his son Xerxes the 1st .
HellasPersia never conquered the whole of Greece and the bits that medized (submitted to Persia) were quickly intimidated back away by the major powers of Athens and Sparta. Persia kept trying to conquer Greece because, simply, it was described to Darius and Xerxes as the most beautiful place in the world, and they wanted it.
He wanted to increase the wealth of Persia, he wanted glory, and revenge.-------------------------------It all began when the Greeks helped the Ionions revolt, which resulted in the destruction of the Persian city of Sardis. Darius the Great swore revenge, ordered his satrap to attack Greece, but failed. Darius took the task upon himself, but soon died. His son, Xerxes the Great, continued his father's plan.It is important to note that Xerxes did NOT want to conquer Greece. After the Persian victory at the Battle of Thermopylae, Athens was abandoned and "conquered" by the Persians, but Xerxes decided to burn it to the ground in revenge for what the Greeks did to Sardis (although soon after, Xerxes regretted what he had done and rebuilt the city), and thereafter soon left Greece.
They did not conquer Greece. They had incorporated the Greek city-states in Asia Minor into their empire, but their attempts to bring the rest of the Greek world under Persian control failed. The reason they wanted to control the mainland cities was to stop the Greek cities creating disruption in their empire with their constant fighting amongst each other, which spilled over into territory ruled by Persia.
because Darius wanted his only full son to be a great king like him and he wanted him to be wealthy like him
First it was Darius the Great, and after he died it was taken on by his son Xerxes.
Xerxes was the Persian king, who wanted to take over Greece. Leonidas was the king of Sparta, who was one of many to defend Greece. It's pretty obvious why they were enemies.
They belived the world was theirs and they wanted to conquer it. (please improve my answer if needed.)
Phillip the second did. he did it in order to conquer Persia. he wanted to prove that his army was strong enough to conquer Persia and maybe even beat Greece's army.
He didn't invade Greece - he sent a punitive expedition against Athens and Eretria, both of which had supported the uprising of Miletus in Asia Minor against Persian rule. In the process, the Athenian and Eretrian forces had burnt the provincial Persian capital of Sardis. After the partial failure of this punitive expedition of 490 BCE against Eretria (captured, inhabitants enslaved) and Athens (turned back at Marathon), Darius determined to bring mainland Greece within his empire. As the mainland cities had been supporting revolts by other Greek cities within his empire (not only Athens and Eretria), he thought that, by absorbing mainland Greece, he would establish an ethnic frontier in the west. He therefore determined to bring whatever cities he could under his rule peacefully (by bribes, and promise to make a faction in a city to be rulers under his rule, ie puppets). Those who resisted would be captured, and puppet rulers imposed on them. He was temporarily diverted by an uprising in Egypt, and then died without launching the expedition. His son Xerxes began to carry it out in 480 BCE.
Darius wanted revenge.
Adolf Hitler wanted to conquer the world. Also Ghengis Kahn and his successors.
